Because they haven’t, and that shouldn’t come as a surprise. After all, I once tried really hard to convince myself that AVP: Alien vs. Predator was not a colossal disappointment that made my soul hurt, and if that doesn’t speak to the lengths my love of the Alien franchise will take me, then you’ve obviously never seen AVP: Alien vs. Predator, and oh how I envy your unsullied eyes.

Anyways, ComingSoon.net has picked up on a story from Shadow Locked in which Roger Christian (who was art-director for the original Alien) claims that Ridley Scott’s intending to make his upcoming Alien prequel in 3-D, though I’ll let his own words take it from here:

Ridley’s doing the next Alien in 3D. Ridley told me some of his ideas when we were here in Toronto. He has a very clear understanding of where this should go. They kind of stopped dead one of the greatest horror franchises there’s ever been, and it had legs to go on. So I’m hoping he’ll revive another three. The world certainly wants it, and the fans want it – everybody.

Sure, Hollywood’s current obsession with making every potential blockbuster a 3-D spectacular already has me near fatigue, but Alien built its tension through its brilliant use of space, which means I can’t even imagine the throes of ecstasy that Ridley Scott moving his camera through a cavernous, Nostromo-esque ship will bring when it’s in 3-D. Seriously, I really can’t handle news this nerdgasmic, so I’ll just let my Photoshop Skillz speak on my behalf:

Indubitably.

In fact, my sole concern about a 3-D Alien prequel at this point is that 3-D could make me barf when I go see this in theaters. That would be all sorts of embarrassing. Barfing from excitement, however, is only inevitable.
